Feeding habits of hatchery-reared grouper, Epinephelus suillus larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The feeding habits of hatchery-reared Epinephelus suillus larvae were determined by examining their gut contents. The larvae (2.6 mm TL) were initially fed rotifers on day 2 and newly-hatched Artemia nauplii on day 21 (9.1 ...
Seafarming and searanching in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1994)
Seafarming is undertaken in the coastal sublittoral zone. Different marine organisms such as molluscs, estuarine fishes, shrimps (pen culture), and seaweeds are cultured along the coast of Thailand. Seafarming, especially ...
Ecological impacts of seafarming and searanching
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1994)
Seafarming has ecological effects such as pollution and eutrophication of adjacent areas by excess food or by feces or modification of habitats by physical structures. More subtle effects on the communities result from ...
Tilapia breeding and seed production for brackishwater culture in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Tilapias are important foodfishes in the Philippines second only to milkfish. While farming of tilapias in freshwater ponds and cages is already established, there is a need for wider application of the available technologies ...
Mass larval rearing technology of marine finfish in Japan
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
With economic development and increased demand for high price fish, industrial scale marine finfish culture in Japan was started in 1960-1965 for yellowtail Seriola quinqueradiata. Sustainable supply of wild juvenile and ...
Successful use of cryopreserved oyster trocophores as a live first feed larval marine fish and invertebrates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Trochophore-stage larvae of the Pacific oyster Crassostrea gigas were cryopreserved in bulk and stored in liquid nitrogen for periods up to two years before thawing and feeding to a variety of warmwater and coldwater larval ...
Correlations of oocyte diameter with some morphometric characters in the nile tilapia, Oreochromis niloticus L.
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
A study was conducted to determine the correlation of oocyte diameter with some morphometric characters in a Philippine strain of Oreochromis niloticus L. One hundred and thirty-five 7- to 9-month old sexually mature female ...
Research on seaweeds and mollusks
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1995)
Research on seaweeds focused on the carrageenan-producing Kappaphycus alvarezii and the agar-producing Gracilaria spp. Growth of K. alvarezii was better on horizontal lines than on vertical or cluster lines from bamboo ...
Influence of LHRHa and methyltestosterone on milt production of sea bass Lates calcarifer (Bloch)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Milt volume, sperm density, and number of spermatozoa were determined to quantify milt production of mature sea bass after a single injection of LHRHa [(D-Ala6,Pro9-N-ethylamiide)LHRH] in saline solution and 17α-methyltestosterone ...
Nickel-induced pathohistologic alterations in Oreochromis mossambicus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
A pathohistologic study was conducted to determine the effects of nickel on the testes of maturing Mozambique tilapia, Oreochromis mossambicus. The fish were treated with 0.5 mg/L and 1.0 mg/L sublethal dose of nickel ...
